　　The recall may hurt Symbion Inc, maker of the Jarvik-7, but it wont end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection . Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patients chest. The first sample products arent expected for another 10 or 20 years. But some people are already worrying that theyll work - and that Americas overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nations health.
